(This is NOT an APP REVIEW, I created Power Planner and am demoing it)

Power Planner is hands down the best homework planner app for Windows Phone. With features like automatic reminders, the fastest homework entry system, multiple live tiles, a tile to display when and where your next class is, a gpa/grade calculator, hyperlink detection, online backup/restore, attaching pictures to homework assignments, and much more, it can't be beat!
